Kuchepetsa Gawo la Msika Losakwana - 70% mu Zingwe Zachitetezo Zamkati mwa Mgodi wa Malasha ku Australia | Chingwe cha Dingzun
Gawo la migodi ku Australia limagwira ntchito motsatira malamulo ena okhwima kwambiri padziko lonse lapansi okhudza chitetezo (AS/NZS 60079.11). Kasitomala wathu, yemwe amagwira ntchito yokonza malasha ku Queensland, anakumana ndi mavuto awiri akuluakulu:
- Kukhulupirika kwa Chizindikiro: Zingwe zodziwika bwino zolumikizira zida zinayambitsa kusuntha kwa ma signal pa mtunda wa mamita 500 chifukwa cha mphamvu zambiri, zomwe zinapangitsa kuti ma signal asamawerengedwe bwino.
- Chiwopsezo cha Unyolo Wopereka Zinthu: Kuchedwa kwa kayendetsedwe ka zinthu padziko lonse lapansi kunaika pangozi kupitiriza kwawo kugwira ntchito.
Iwo ankafuna mnzawo, osati wogulitsa yekha—yemwe ali ndi Zaka zoposa 20 zachitukuko ndi ukatswiri wozama mu Chitetezo cha Mkati (Ex-i) uinjiniya.
Tinatumiza Mndandanda wa DZ-IS-Mining (Chingwe Chotetezeka Mwachilengedwe / Cholumikizira Zida)Gulu lathu laukadaulo silinangopereka mawaya okha, koma linaperekanso Kuwerengera kwa Lingaliro la Bungwe kuonetsetsa kuti magawo a chingwe akugwirizana bwino ndi zotchinga zawo.
Kuti tipulumuke m'malo ovuta a ku Australia ndikukwaniritsa miyezo ya IEC 60079-11, tidasintha magawo otsatirawa:
| Chizindikiro | Chingwe Chokhazikika | Chingwe cha Migodi cha Dingzun DZ-IS | Zotsatira |
|---|---|---|---|
| Mphamvu yamagetsi (Cc) | >180 nF/km | ≤150 nF/km | Amalola Kutalikirapo ndi 30% mtunda wotumizira uthenga kuchokera ku chotchinga chachitetezo. |
| Kutulutsa (Lc) | >1.0 mH/km | ≤0.8 mH/km | Zimaletsa kukwera kwa magetsi oopsa panthawi yosintha magetsi. |
| Kuyesa Chitetezo | Ex-ib (Zone 1) | Ex-ia (Zone 0) | Wovomerezeka kuti apeze malo osungira migodi omwe ali pachiwopsezo chachikulu. |
| Mtundu wa Zida | Tepi yachitsulo | GSWA (Galvanized Steel Wire Armor) | Mphamvu yokoka ya 50% yokwera kwambiri pamayendedwe oyima ndi a longiwall. |
| Chigoba chakunja | PVC Yakuda | Buluu Wopepuka (RAL 5015) LSZH | Kuzindikira kotsatira malamulo + kutulutsa utsi wochepa wa poizoni. |

N’chifukwa chiyani kasitomala anasintha 70% ya zomwe anagula n’kupita ku Dingzun? Manambalawa amadzionetsera okha.
| Chiyerekezo cha Magwiridwe Antchito | Zotsatira | Chizindikiro cha Makampani |
|---|---|---|
| Kuchepetsa Chizindikiro @ 1MHz | 6.8 dB/100m | ≤ 8.5 dB/100m |
| Kubwerera kwa Moto | Yadutsa IEC 60332-3-22 (Cat A) | Yadutsa (Standard Cat C) |
| Moyo Wosinthasintha (Wopindika) | Ma cycle 2.5 miliyoni | Mizunguliro ya 1 miliyoni |
| Kuteteza Mphamvu | Kuphimba kwa 95% (TCWB) | Kuphimba kwa 85% (Foil yokha) |
Potsatira IEC 60079-14, tinapereka Buluu Wopepuka (RAL 5015) Zingwe zomangidwa ndi jekete. Chizindikiro ichi chodziwika bwino chimaonetsetsa kuti akatswiri amagetsi a m'migodi sagwirizanitsa mwangozi ma circuits a IS (Intrinsically Safe) ndi ma powerlines osakhala a IS, chinthu chofunikira kwambiri pachitetezo m'malo omwe pansi pa nthaka sipakhala kuwala kwenikweni.
Pambuyo pa miyezi 6 yoyesa kwambiri mgodi, mgodi waku Australia unanena kuti:
- Kulondola kwa Chizindikiro 100%: Kutseka kwa magetsi kopanda chifukwa cha phokoso lamagetsi (EMI).
- Nthawi Yochepa Yopuma: Zida za SWA zinachepetsa kuwonongeka kwa chingwe ndi 70%.
- Kuchepetsa Mtengo: Ndasunga 25% mu ndalama zoyendetsera zinthu poyerekeza ndi ogulitsa aku Europe.

Ndi Zaka zoposa 20 zachitukuko monga mtsogoleri Wopanga waku China, Dingzun Cable imagwirizanitsa kupanga ndi luso la malonda (Factory Direct). Sitingopanga waya wokha; timapanga mainjiniya. Chingwe chapamwamba kwambiri chotetezeka komanso chogwiritsa ntchito zida mayankho a malo ovuta kwambiri.

- Mphamvu Yosinthira: Zovala zapakati zomwe zimafanana, zotchingira (AL-PET/CWB), majekete (LSZH/PUR), ndi zida zankhondo (SWA/GSWA).
- Gulu la Akatswiri: Gulu lathu lothandizira paukadaulo limapereka kwaulere Kutsimikizira kwa magawo a bungwe kuonetsetsa kuti dongosolo lanu ndi lotetezeka.
- Ziphaso: Kutsatira malamulo a CE, RoHS, IECEx, ndi AS/NZS kwakonzeka.
Musakonde zingwe zokhazikika zomwe zimaika chitetezo pamavuto.
Pezani mtengo kapena chitsanzo chaulere lero.
